ContinuousQueryListener<int, sample_bank_account::User> cql(testCache,"select id from sample_bank_account.User");
std::function<void(int, sample_bank_account::User)> join = [](int k, sample_bank_account::User u) {
std::cout << "JOINING: key="<< u.id() << " value="<< u.name() << std::endl;
};
std::function<void(int, sample_bank_account::User)> leave =[](int k, sample_bank_account::User u) {
std::cout << "LEAVING: key="<< u.id() << " value="<< u.name() << std::endl;
};
std::function<void(int, sample_bank_account::User)> change =[](int k, sample_bank_account::User u) {
std::cout << "CHANGING: key="<< u.id() << " value="<< u.name() << std::endl;
};
cql.setJoiningListener(join);
cql.setLeavingListener(leave);
cql.setUpdatedListener(change);
testCache.addContinuousQueryListener(cql);
